When a Certain Capacitor Carries Charges Of $\pm 10 \mu \mathrm { C }$

question 5

Multiple Choice

When a certain capacitor carries charges of $\pm 10 \mu \mathrm { C }$ on its plates, the potential difference cross the plates is $25 \mathrm {~V}$ . Which of the following statements about this capacitor are true? (There could be more than one correct choice.)

• A) If we double the charges on the plates to \(\pm 20 \mu \mathrm { C }\), the potential difference across the plates will decrease by a factor of two.
• B) If we double the charges on the plates to \(\pm 20 \mu \mathrm { C }\), the capacitance of the capacitor will also double.
• C) If we double the charges on the plates to \(\pm 20 \mu \mathrm { C }\), the potential difference across the plates will also double.
• D) If we double the charges on the plates to \(\pm 20 \mu \mathrm { C }\), the capacitance of the capacitor will not
